MULTIPLE-BLOCK MOLD.

Application filed July 5,

The invention relates to improvements in cement block molds designed for the formation of a plurality of blocks, and the principal object of the invention is to provide a mold constructed from a plurality of sections which may be assembled to permit the simultaneous molding of a desired number of blocks.

Further objects are to provide unique means for connecting the mold sections with each other and to provide novel means for shaping the tops of the blocks to interfit with the bottoms of overlying blocks.

A still further aim is to provide a construction which will be rather simple and inexpensive, yet will be efficient, reliable and in every way desirable.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Fig. 1 is a perspective view showing a number of the mold sections assembled.

Fig. 2 is a disassembled perspective view of the parts shown in Fig. 1.

Fig. 3 is a transverse sectional View on line 3-3 of Fig. 1.

Fig. 4 is a detail horizontal section substantially on line 4-4 of Fig. 1.

Fig. 5 is a perspective view of one of the blocks formed by the mold.

Fig. 6 is a perspective view showing a number of the blocks laid with others in the formation of a wall.

In the drawings above briefly described, the preferred form of construction has been illustrated. This construction will be.here in specifically described, with the understanding however, that within the scope of the invention as claimed, variations may be made.

The numeral 6 designates a relatively long rectangular side wall reinforced at its upper and lower edges by angle metal 78. Disposed in spaced parallel relation with the long side wall 6, is a relatively short wall 9. One transverse wall 10 is rigidly joined to one end. of the short side wall 9, and projects laterally in one direction therefrom, to one end of said side wall .6. Rigidly joined to the other end of the short side wall 9, is a second transverse wall 11 which projects in the opposite direction from the wall 10, saidone trans verse wall 10 and said second transverse wall 1927. Serial No. 203,652.

11 being preferably of substantially plano- A second relatively long longitudinal wall 6 is laterally spaced from the free edges of the transverse walls 11 and 12, in overlapping relationwith the long side wall 6. A

second relatively short side wall 9 is dis Y posed in spaced parallel relation with the long side Wall 6 and one end of this second short wall 9 is provided with a fourth transverse wall 13 which is rigidly joinedthereto and projects laterally to one end of the second long side wall 6 The other endof the second short wall 9 is provided with a fifth transverse wall 14, rigidly attached to said wall 9 'and projecting laterally therefrom into overlapping relation with the third transverse wall 12. The other end of the second long side wall 6 that is the end remote from the fourth transverse wall 13, is provided with a sixth transverse wall 15 which is'rigidly joined thereto and projects therefrom into overlapping relation with the second transverse wall -11.

The two long side walls 66 and the six transverse walls 101112-131415, to-

gether with certain connecting means here ina-fter described, provide a mold which will form one block, and port-ions of-this mold co-opcrate with other mold' sections hereinafter describechin the formation of a second block. Similarly, these last named mold sections may be coupled to others to form still other blocks and the line ofmolds may be extended to'any desired length.

, A third relatively long side wall 6 is outwardly spaced from the second short side wall 9 and abuts the third transverse wall 12, being'connected thereto by means hereinafter explained. side wall 6 is disposed in overlap-ping'relation with the wall 6 and is provided at one end with a seventh transverse wall '16 which is rigidly attached to said wall 6 and extends into overlapping relation with the fourth transverse wall 13, being interposed between this wall 13 and the adjacent end of the second long side wall 6"-. Hence, the same relation which exists between the third trans- A fourth relatively long I Verse wall 12, the fifth transverse wall 13 and the third long sidewall 6", exists between the second long side wall 6 the fourth transverse wall 13and the seventh transverse wall 16. An eighth transverse wall 17 has been shown rigidly joined to the wall 6 and projecting therefrom toward the wall 6.

Upper and lower lugs 18 and an eye 19 are formed at the free'ed'ge'of'eachof the transverse Walls 10, 11, 13 and 14. The free edge portion of'each of thetr'arisv erse walls 12, 15,16 and 17,'is ferined with upper and lhwer roups of slots 18? andhetween'said slots wlth another slot 19. The ends of the relatively long side wa llsfi, 6, 6 and G, remote from the last named transverse walls, are each provided with a l-ateralfflan g'e'or lug Q'QhaVing slots .21 and 21 Pi v ote-dt'o each ofthe's'elengside walls, near the lug 20,'is"an"ai'm22 whose piyot is such as to also permit lengitudinal sliding of said arm. The freeend of this arm carries one or more wage as. r. a

.To conne t' the transverse walls 12 14 withfeachf other and With the third long side wall 6 ,the lu gs.'1"8 of the liftlrtransverse wall 14 are passed thr'ough the slots 18" of he transverse wall 12,"andthro'uglrslots 21 of lug 20 'oflwall 6 theeye'19 of said wall 151 isl pas'sed, thro 'igh. the. slot 19 of the wall 12 also. through the slot 21 in thelug; 20 of thethird long sidewall 6 7 Then, the Wedge 23 .associatedwith this side wall, is forced or driyenthrough the eye as shown at the central portion of Fig. 1.

The transverse walls'11- 15 are connected Witlreach other merely by passing'the lugs 18 and the eye 19 of the wall 11 through the slots 18 19? of the wall 15. If desired,.hoW- ever, a wedge or the like may then be inserted through the eye. I V

The s cond long side wall 6 the fourth transverse wall 13 a nd the seventh transverse wall 16, are connected with each other in exactlythe same manner-as the Walls 12-146", are. connected. I

While the reinforcements: 7-.8 have been described only'in connection with the long side Wall 6 and the attached transverse wall 12,111Willb6 observed that this same construction' is duplicated with other sections of the mold Bot-hthe upper and lower angle bars are formed with slots 24 and ,the slots of the lower bars are enga-geable with lugs 25 on a base 26, assisting in properly. positioning the moldsections on said base. Inthis connection, it may be stated that the slots 24:, like.

the slots 18 are disposedin groups. This lower portions of the mold sections, these sections may be used with either longitudinal edgecoritaeting with the base.

The mold formations herein disclosed, will p'rothicebloel'tsbf S shape in plan view, as shown in Fig. 5. I prefer to provide both the topandthe bottom of each block with a rib27 and a, re :ess 28, so thatthe blocks may interlock with'ea'ch other when buildinga wall. To form the ribs and rooves; at the botthms of the liloc'lts, depressions 9,9 and ridges 30 are'formed on the base 26. To provide'the ribs'and grooves fOl'hllG tops of the blocks, a plurality of plates such as"th'at shown at 31 inFigs. 1, 2 and 8,"are employ d. Each plate is provided with oppositely pressed portions 3233 -t o"pi"oducetheuflesired formations. This plate is preferably of a diamond shape anditsfour corne'rsare provided with rigidly attached pins 341-. These, pins are receivable in "opefiihgs 35 formed at desired points in the upper'edges of a number of themold' walls.

v lt'will beunde rstfood th'at"nly"a portion of the construction which may he in sonieiinstances used, is herein illustratech'but the remainder of such constrli'ction is merely duplication the portions illustrated and hence need not be sl'iown'or described. It will be obvious however that the 'mol dmay be extended to any desired length for forming the desired number 'of blocks at-a single operation.

' Theblocks produced by the mold form no part of the pies ent'i'nventi'on but are-very advantageous inthe construction otall kinds of walls, it being of course clear thatthey must be used in con'nection with-appropriate corner blocks formed by other desired molding'means. The corner" construction" of the wall may if desiredbe reinforced cementfilleda s shown in Fig. 6, audit will alsobe obvious that the individual blocks'may he reinforce-d if desired. llT'oreo ver, by forming curved, longitudinal walls for the mold, curved bloclts for'silos and theli lremay be cast in said mold.
